any sort of world crisis that happens next will be based on fiat currency being devalued. once this process begins, i give it a week or 2 to unravel. at that point, everyone will realize they have no way to work and be paid for it. face it, the world is not setup for the barter system. example: you work for best buy. the dollar is worth nothing. what do they pay you in? nothing. they aren't setup to pay tens of thousands of employees in anything but dollars.
at that point, i believe there will be an onset of rampant crime, looting, killings, etc. here is where all you vigilantes get to play "z day" games. i think at this point, it will be too much from the world to recover from. once the trust network within currencies and nations is disrupted, its over. there is no recovery, neither nationally or worldwide. the infrastructure will be too broken to repair. its alot to grasp, but if you look at it from an economic standpoint, it will make sense.
